TE LE GRAPHIC PPARATUS.

. Gianni), subject ofthe King of Great Britain and Ireland, residing atGlasgow, Lanarkshire, Scotland, have invented Improvements in orRelating to Telegraphic Apparatus, of which the following is-aspecification.

This invention has referenceA to that'kindi of apparatus for perforatinga tape in accordance withvelectric currents or impulses received over aline wire in the manner usual in automatic W'lieatstone telegraphicreceiving apparatus wherein the punch orpunches used for perforating thetape are operated b v a fluid pressure motor controlled through electro-magnetic mechanism 4that receives the electrical currents orimpulses, `and the cory rect position of the tape, previousto its beingpunched, is insured by correcting means that are caused to act upon ayielding feed wheel and adjust the same in a rotary direction relativelyto the constantly ruiming driving shaft used to feed 'the tape throughthe apparatus, the successive operations ot' correcting, punching andreleasing the tape being performed so quickly that the time during whichthe rotation of the feed wheel is stopped, is practically negligible. p

Now the present invention has forits object to further improve theconstruction and working of telegraphic apparatus of the kind referredto for producing practicallyT perfect perforated -Wlieatstone tape Vfromelectric currents, impulses or signals (hereinafter 'called currents)received froin'a distant sta- Vin opposite directions by currents from aseparate electric generator (hereinafter'called the local battery) thatis under the control of a relay in the line wire over which the electriccurrents to be reproduced as perforations in a tape are sent, the localcircuit of the saidl electroanagnetic device being further controlled byan automatic circuit making and breaking device that is under thecontrol 'of the said armature, the arrangement;

being such that the currents passing through the elec-tio-riiagi'ieticdevice are reduced to or cut off at unit length, no matter in whatHorder or manner theyv arrive through the line relay.

In the accompanying illustrative draxw ings, Figures l and 2 areelevations at right angles to one another, and Fig. 3 a plan, showingone arrangement of telegraphic apparatusembodying the presentinveiit'ionka casing inclosing some o' the parts being in section. Figs.4, 5 and 6 are diagrammatic views showing electrical connections, andFigs. 7, 8 and 9 are detail views of mechanical .parts.. Figs. 10 and 11show respectively iii front and rear elevation and 12 in section on theline A A of Fig. 10, a punch block and attached parts.. Fig. 13 is adetail view showing a modilication.

In the arrangement of apparatus illustrated, the electro-magnetic devicecomprises two pairs of electro-magnets a., al and I), b1, and a pivoteddouble armature comprising two iron bars c, c that are connectedtogether by yokes c2 by which they areA mounted to turn on a spindle dwhich is su ported vertically in a frame or holder f.' T 1e y soft ironcores ol" the electro-magnets a., al are connected together by an ironyoke a2, and the cores of the electro-magnets b, b1 are connectedtogether by an-iron yoke b2. windings of the magnets a. al, l) b1 areconnected in series, as shown diagrammatically in Fig. 4, so as to formpractically a single winding which at one end is connected to a terminal3 and thence as shown in Fig. 5 to the pivoted tongue e of a sensitiverelay E which is controlled by the line currents transmittedby the linewire El from a distant station, and which may be ot the ordinary postoffice standard type, the other end. of the magnet winding beingconnected through a terminal 4 to the pivoted contact lever g of acircuit making and breaking device. As shown, the armature c 'c1 ismounted to turn about an. axis located in a plane between the poles ofthe magnets c l) and al b1 so that first one of. its arms, viz., r, canbe attracted by the poles of magnets c b and afterwards its other arm,viz., c1', can be attractedby the poles of magnets c bl and thereby becaused to turn or move alternately in opposite directions. The cores ofthe magnetsv a c1 may, as shown, be arranged horizontally and above thecores of the magnets b b1 and be rendered duced; an

.can be variously constructed.

vthrough itl in one direction will cause the north and south polarity ofmagnets a and b respectively to be increased'and the north an southpolarity of magnets a1 b1 to be rea current passing in the reversedirection will increase the north and south polarity of magnets al b1and reduce the north and south polarity of magnets t b for the purposeof causing the armature c c1 to m`ove alternately and sharply inopposite din rections. The pivoted tongue e of the relay is .mounted tooscillate between two .fixed contacts (i, il. l

The circuit making and breakingdevice In the example shown in' Figs. 1,.2, 3, 5, and 6, it comprises a vulcanite rod p mounted u on. the upperend ot the armature spindle r which projects upwards through the coverplate f1 of the magnet supporting frame the rod p being fix-ed to thespindle by means of'screws.

p1. A screw p? passes through the rod p well abovethe top end of thespindle d and is `screwed into a metal block g between which andaflattened face p3 on the vulcanite 4rod p is tightly clamped a thin flatspring blade g carrying avtits 'extremities two electrical contacts t,t1, the said spring blade constituting the pivoted contact lever ghereinbefore referred to. 'A bent piece of brass u. is also clamped bythe screw p2 in the position shown, in order to ermit of the attachmentthereto and imme iately over the center of motion of the s indle d andcontact lever g,

of a wire 'v whic is connected to the terminal' I 4.

The vulcanite rod p serves tol prevent any electrical connection betweenthe armature spindle d and contact lever g.

The two movable contacts t, t1 on the spring blade g are ada )tedl tomake electrical connection with two ixed contacts w, w1 respectivelyformed on the ends of screws :r1 which are mounted 'in a vulcanite blockmv for the purpose of insulation, the movements of the armature c c"serving to cause contact to be made between the spring blade g and thelscrews a', :t1 alternately. The ends ot the springr blade g arepreferably sprung slightly towards the block q, thus causing them tobear irmly against the same", but when either of the contacts t, t' ismoved against the corresponding contact 'w or w1, the movement of thearmature spindle d is easily able to bend the spring blade g away fromthe correspond.-

l ing end ot the block g. When contact is device.

arrangement described permits the periods ot' electric connection to beprolonged lor any desired time, and the slight rubbing movement producedbetween the surfaces ol the contacts tw and t] w* upon breakingconnection,l and due to the play ot' the spring blade g, keeps thesurfaces of the contacts clean. The block m is fixed to thecover-platejh1 of the magnet frame f by a screw m1 and two steady-pins(not shown). Screws m2, im" serve for clampingconnecting wires v1 and v2respectively to twometal rods e, z (indicated\by dotted lines in Figi),which slide in holes bored vertically throughvthe block m. The contactscrews w1 are screwed through the metal rods 2, z, respectively, thearrangement being such that when the screws m2', mi* are tightened uponvthe connecting wires o1, o2, they will )ullthe rods z, .el towards thetop of the block m, and thus lock the screws in place. The screws x1 arethus electrically connected with the wires 12,1 v2, which are in turnconnected respec tively with the binding screws 1 and 2 on tacts il andw1 are similarly connected to 9 gether and to the other pole of thelocal battery r through another conductor Z1 that may also include aresistance device al, such as a coil. A condenser. n2 is preferablyconnected to the tern'iinals 3 and 4 across the ends of the magnetwinding to prevent sparking at the contacts.

The construction and arrangement ofthe apparatus is such that assumingthe last signal received from the line wire E1 by ther relay E was aspacing current, then the relay tongue e will have been caused to cometo rest against the relay contact i and the local circuit closed andopened, and the contact t y on the contact lever g will be restingagainst contact w ot' the circuit 'making and breaking `lf now a markingcurrent arrives, the relay tongue e will be moved into connection withthe relay contact 'il and will causen 4current to low from one pole ofthe local batteryv r through 'the conductor l and resistance device n,contacts w and tand contact lever g, the winding of magnets b1, al, aand b, and terminal 3 to the relay tongue e and thence 'through contactt1 and the conductonZ1 to the second pole ot the bat' tery. Theelectro-magnetic device (a, a1, t, b) will then be energized so that thearmature. bar cl will be attracted by the magnets f1.1 bl, and, after a`little more than one haltl of the movement ol' the armature has beenmade, it will move the contact lever g so as to break the local circuitbetween contacts w and t and cause contact t1 to bear against ser/,e 13

until the rel-ay tongue e is caused by the acf- *tionof a line currentin'the reverse direction #to again bear against the relay contact i,"fwiihereupon a momen-tary current in the re- "'fnetwindiiig. When thistakes place, a curf rent will flow from the local battery lc inthereverse direction through the inagnet winding by way of the firstmentioned conductor '10 Z, relay contact i, relay tongue e, magnetwinding, contact lever g, contacts-t1, w1, and the secondly mentionedconductor Z1 and resistancev coil nl, `whereby 'the magnets will movethe armature c, c1 in therevers'e direc- 1 1-'5 tion'and cause it toinove the contact .t1 froin contact w1" and cause 'contact t to bearagainst Contacta), the'parts-'being then in the posi tions first'mentioned i By the arrangement"V described it will be;u-'ndeistood-thatno matter how long the re- ,lavtonguee i'nay rernainagainst either ol the re ayconta-cts i il, no current will liow throughthe-magnet windings except the temporary or.` initial current of unitlength necessary to operi'xtetlie armature. Furtherniore,tliearrangement' not only saves current but what is or great importance, itenables powerful currents lcapable of producing 4strong 'and' Shar 'resonse of the magnets to lbe used without a lowing such current to flowfor a ends of the screws a', 9:1, the duration vof theV low of electriccurrent can be regulated by endwise adjustment of the screws. Thearrangement shown in Fig. 6 is sini pler than that shown in F 1g. 5, asin this 'case only one resistance coil e is necessary, the

battery lc being placedv in such aposition be tweenthe tongue c and thecontact lever g that it -is impossible for it to be short-cir cuitedinthe process of working the apparatus. .ln this arrangement, when thetongue @comes into connection with Contact i, a current from the batteryla passes through con- .tvacts w and t and the coils of magnets a andalone to.contact e, and thence to the other g-lpole of the battery. Thecurrent in passing 55 through the winding of magnets a, Zi may becaused'either to decreaseor increase the pull of the cores for thepurpose of breaking the circuit' between contacts w .and t, but in thefigure shown it is arranged to work by diminution of pull. The circuitwould iu any case be broken between contactsw and t and be remadebetween contacts yw1 and 251 but would be op'en between the tongue e andcon- 'tact ilj On the tongue e being i'noved against contact il, thecurrent freinl the battery .if

'f'fverse direction will be sent through the mag The resistance coils n,

will ass through contacts w and t1 and the win. ing oi inagi'iets c andlil alone, and li'nd its way back to the otherpole of the batterythrough Contact il, the magnets 0L, b remaining idle, and the circuitbeing o'f course again broken between contacts #and w by the diminutionof the pull olE the magnets (L1, lil. While this arrangcinei'it hascertain obvious advantages, it is thought that Where high voltages areavailable, the arrangement shown in Fig. 5 is preferable, seeing thatthe lrevi'irsal ol current through pthe windiiigs'of the magnets has theetlect of instantly sweeping out the residual charge, whereas in thearrangement shown in Fig. 6; the windings tend to become over-chargedwith working. In the arrangement shown in Fig. 6', a resistance n in thebattery circuit is not really necessary. .y

The valvetcontrols .the supplyof compressed air to and its exhaust troni each endof the niotor cylinder, 5b being the-.air inlet, and the exhaust beingdirect tothe external atmosphere through 'the valve case. The piston rod6 of the inotorextends through both ends of the motor cylinder, andagainst each of its ends bears one arm 7 j of a three armed bell cranklever 7 a, 7b, 7c, the two levers being pivoted upon heavy studs 8 andconnected together by a rod 9 that is jointed to one of the other'arins(viz. 7b) of each lever.l To each of the third arms 7 of each bell cranklever is pivoted` a striker in the forni of a lever 10 10l (Figs. 3 and9) one arni, viz; 10a, of which is connectedby a spring 11 to the arni7'1 of the cru-responding bell crank lever, and the other ariii,viz.10,- of which is adapted to abut vagainst the rear end or head 12*L of acorresponding correcting device that inay, as shown, be iii'the forni ofa rod 12, and alsov against the rear end or head ,13? of a corresponding)unch 13. For this purpose the 'tree end c' thel striker' arin 1() inaybe forked as shown in Figs. 3 and 9, the pr ng 10b being arranged toengage the head 12a ofthe correspoi'iding rod 1.2, and the prong 10 be-ving arranged to engage thehead 13a oi the. correspoi'iding punch 1 3,the two prongs bee, ing connected by a/cross bar 10d. The two correctingrods'lZ and the two punches 13 are iuounted to slide horizontally in aliai'-,

The roar ond or head 13 of each punch 13 is similarlyformed and controlled by a slide plate 171e,v4 tho two punches beingarranged parallel to the correcting rods 12 but at a lower level, asshown in Fig. 1. The correcting rods and punches are normally heldintheir backward or ret'ractcd 'positions by bent spring blades 18 andluthat are arranged within and extend upward through a hole -14f in theblock 14. Between the 'two striker arms 1() is a fixed stop orstationary abutment 20 (Fig. 3) against which the cross bar 10d of eachstriker arm 10 in turn can be held by the corresponding spring' 11 so asto hold the prongs l()b and 1()c of such striker respectivelyin linewith the corresponding correcting rod 12 and punch 13. Between the twostriker arms 10 and carried by the rod 9, is a tappet 21 adapted toengage the. cross piece 10 of each striker arm 1() in turn.

The feed wheel spindle 15 is driven by friction 1from suitable drivingmechanism. For this purpose the spindle may be provided with a frictionwheel 22against diametrically op posite parts of the periphery of whichbear two small friction blocks 23 carried by two arms 24' that arejointed at one end -to a rotary carrier 25 and are connected together byan adjustable spring 26 by means of which the degree of friction betweenthe friction Wheel 22 and blocks 23 can be varied to suit requirement.`The rotary carrier 25 in the example is fixed to the shaft 27 of' atoothed Wheel 28 which gears with the pinion 29 connected to afriction'disk 30 against the face of which bears the periphery of africtional driving wheel 3'1-consisting for'example of a disk of indiarubber or leather fixed between collars 31a, 3,11 on the shaft 32 of amotor `33, for example an ,electric motor,

ythat is adapted by screw adjustment to be moved endwise for moving thedriving wheel 31 horizontally across the face of the friction disk 3()in order to adjust. the speed of rotation of thov feed wheel spindle 15to 'suit requirement. lhe motor 33 .maybe moved cndwise by fixing it toa block 34 that is arraiiged'vto slide in fixed guideways 35 and intowhich works the screw threaded end of a spindle 3G that is prevt-fntodfrom moving endwisc, as by the 4point ol' a fixed screw 37 'entering anannular groove 37'a in its periphery, and which can be. rotated, whenlrequired, by a crank handle to effect the desired endwise movement ofthe motor-33 and driving wheel 31. The disk 30 is kept in drivingcontact withthe driving wheel 31 by a spring 31 bearing against the endof the spindle 30 carrying tlfie said disk and the hub or pinion 29.

The arrangement 1s such that Wherrthe l motor piston 6 moved, say to theright, by the movement of the valve 5a to the left under tho control ofa linecurrent and the larmature c, c, the'left hand striker arm 10,

which will bei thon pressed by its spring 11 against one side of thestationary abutment 20, so that its prongs 10h, 10C are in line withtheI left hand correcting rod 12 and punch 13, lwill be moved forward bythe corresponding bell crank lever T', 7b, 7c through the rod 9 and thcright. hand bcll crank lever 7a, 7b, 7", so as to cause the prong 1()hto' move the correcting rod 12 forward and cause the front end 12"1 ofsuch rod to adjust the corresponding correcting wheel 16, feed wheel 17and tape C, -if-this should be necessary, and then cause thc prong 1()Cof the said arm to oper ate the corresponding punch'13 to perforate thetape C, the adjustment for punching being completed at about half thestroke of the striker arm, the part 12b of the correcting rod slidingfurther into the recess 16* of vthe corresponding correcting wheel 1Gduring the further operatiim ol' punching. The prongs 11), 10" of thestriker' 10--10l will'then be moved out of contact with the correctingrod 12 and punch 13 by the tappeti 21 moving to the left, so as to allowof the correcting rod 12 and punch 13 quicklj making?. their returnstrokes under the. action of their springs 18 and 19. During thisaction, the right hand striker arm 1u, which was previously moved intothe inoperative position b v movement of the tappet. 21 to the right,will be returned to its initial or starting position by its bell cranklever 7, 7b, 7 and be pressed `against the stationary abutment 2() bj'its spring 11 so that its prongs 10b and 1(1 will be again brought rospectivel \v into lin'e with the right hand correcting rod 12 and punch13.. Willen the valve 5 is moved' inthe opposite direc tion, viz. to theright, by the action of a line current in the reverso direction and thearmature c. cl, 'find thc motor piston 64 therebvcausml. to moveto theleft, the left 353%? 31%? effi hell crank lever 7', 755,' 7 e. willvcau-se the prongs '10?, 10 of the -right hand striker .IiP-10 to act insuccession upon the right hand correcting rod `12 'and punch 13 andvcause' these tornake their forward operative strokes for the pur ososherein-before described, the said-'strilier arm 10 being then moved intothe inoperative position by the movement of the tappet 21 to the rightso as to allov'fthe rod 12 and punch 13 to snap hack'into theirinoperative positions; Dur

sol -4 th'e teeth of the correcting .Wheel `16 just before thel point ofthe corresponding punch 13 in this movement, "the left-hand striker 110a will be again returned to its initial or starting position bytheleft hand bell crank lever 7Bf, 7b, 7c and be again pressed against thestationary abutment 20 by its spring'll vso that its prongs 10b, 10Cwill again-be in line'respectively `with T the left hand correcting rod12 and punch 13 in readiness for the next operation of the motor 5.l

To-enable'the position ofthe feed wheel 1 7 andtape C to be corrected ingood time for punching, 'as hereinb'efore described, the

o erative end or tooth 12b of each synchronizing rod 12 is provided (seeFig. 7.) with a paral el part adjacent to the rear end vofthe v -shapedpoint, and such part is arranged to enter a corresponding parallel partvat the bottoniA of each ti-'shaped recess 16* ,between touches the ta eC.' Inorder to avoid cutting the parel el portions of the recesses inthe' correcting wheels 16 too deep and thus weakening these wheels, thetappetl on the eonnectingrod 9 vmay be arranged to knock each strikerarm 10 in turn of? the head 12 of the corresponding correcting rod 12about one thirty second of vaninchv sooner than. it clears the head '13.ofthe corresponding punch 13, thus enabling the punch to malte a fullstroke. This result can beattained by making the heads 13@ of thepunches 13 a little broader thanthe heads 12 of the correcting rods 12.The apparatus will however work satisiactorilywhen each punch 13 andthel corresl sponding correcting rod 12 clear the correuspondi'ng'striker 10-10 at the same time, but the arrangement describedis considered better as 'it also providcsfor wear ol' the the correctingrods 12 will engage correcting partsg- .Each punchrod mayconvf-:niently,l

and as' shown, -be .made of round wire ilat tened and shaped at one end3 to receive the blow of the corresponding striker and be formed at theothci1 or front end with a cen? tral hole to receive the 'correspondingpunch 13 or point whichis or may be of hard steel. Each correcting rod12 may'alsobe similarly formed. The correcting rods. 12 and punch rodslSareso arranged that th'epoints 12b of .wheels 156 arranged-at oppositesides of the feed wheel 17 ,i while. the punches 13 will per- 'foratethe tapeC at'opposite sides ofthe central row' of feed holes therein.l.hdiust'able buffers 38 may be provided to adyust the' travel of thebellcranl: levers 7a, 7l?, 70 and attached parts. and to reducenoise. Bythe arrangement described, each corn rooting device is rendered simplerand stronger in construction andrnore positive'and direct in operationthan is the ease 1n the' arrangements heretotore used. Each punch 13 maybe connected to thecorresponding correcting device 12 by a common head.13et (Fig- 13) so' that it would he impossible for one of such parts tomaire either'its forward stroke or its return stroke without the otherpart. By making the parts separate how-f ever, as describedand shown,better provi sion. is made for wear thereof.

Various sections or parts of the apparatus hereinbeiore described are soconstructed .and arranged as to be readily detachable and exchangeable.For instance, the die block 14 which carries the correcting rods 12 andpunches 13 is so arranged that by the re-4 Y un'ch holes in the dieplate and are provided lor the purpose oli' leading out tl'iecuttingsanddischarging them into a chute 42.

pposite the punches 13' may be iirred' a.. ook 40 containing two holes41 which form practically an enlarged extension of the chute 4 2, ismounted on. standard. 43 and is provided with'two plates 44 and 45, oneof which viz., 44 serves as a cover, and. the other 45 has its upper endshaped and errnogerdl to strip the tape C off the feeder/heel 17 anddischarge it as shown. The tape reel 46 is mounted in a drawerunderneath the appa:

ratus, as indicated by the dotted lines in Fig. 1, and moans areprovided for leading the tape from the reel into the slot or passage 14*between the die block 14 and die plate 1.4. .The machine is mounted uponthe inner wooden base B which is separated from the larger base D byathick iayer F ot lelt,and a cover not shown, is provided, also linedwith. felt, which servesv the purpose of silencing the noise of working.A. metal cover G shown. in section. in Figs. l, 2 and 3, is pro vided toprevent 'the oil spray thrown up by thieme-chine in working, from beingcarried. to other parts oi' the apparatus.

As will be obvious the details of construction can. he variouslymodified. Thus,4 the forward end of'each punch 13 may be supported inrahardcollet 'or tube 13rr that can mode of operation describe electricabe conveniently'removed when worn and replaced by a new one, and thecutting die may be 'ormed by a thin removable hard. steel plate lag'ixedto the die plate 14, Also "it will be evident .that various changes canbe made in. the construction of the apparatus 'hereinbefore describedWithout de parting from, the spiritandscope of the inventionjso long asthe relative arrangement of the mainparts of the apA aratus, or the d),is preserved.
